1) Overall sales in December were up 0.7% year-over-year (including homes, condos and manufactured homes).

2) Active inventory is now down 12.6% year-over-year.

More inventory (a theme in most of 2014) - and less investor buying - suggested price increases would slow in 2014. And prices increases did slow in 2014, only increasing 2.4% according to Case-Shiller.

In 2015, with falling inventory, prices increased a little faster. Prices were up 6.3% in 2015 according to Case-Shiller.

With flat inventory in 2016, prices were up 4.8%.

This is the fourteenth consecutive month with a YoY decrease in inventory, and prices are rising a little faster in 2017 (4.9% through October or 5.9% annual rate).
